CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 336,232, dated February16, 1886.

Application tiled October 29, 1885. Serial No. 181,214. (No model.)

To all whom t may concern:

Be it known that I, GEORGE B. HATNEs, of Chicago, county of Cook, andState of Illinois, have invented certain new and useful Improvements inCar-Starters, of which the following is a full, clear, and exactdescription, that will enable others to make and use the saine,reference being had to the accompanying drawings, forming a part of thisspecification.

rIbis invention relates to an improved device for assisting the horsesor other motive power in starting a street-car and in overcoming thedead stop or weight of the same, as will be hereinafter set forth.

Figure l is a plan of the under side of acar embodying my improvedfeatures; Fig. 2, a "ertical central longitudinal section; Fig. 3, anenlarged detail; Fig. 4, a transverse sectional detail in the plane44,Fig. 5; and Fig. 5, a longitudinal section in the plane 5 5, Fig. 4.

Referring to the drawings, A represents the under side of a car, A A2the car-axles, and A3 the truck-wheels.

In Fig. 1 two draw-bars are shown and the improvement illustrated induplicate. This arrangement provides means for the car being drawn fromeither end, and also the coupling together'of two ormore cars, ascircumstances may require.

When the car is turned around at each end of the route, but one bar isnecessary. When a ear is provided with two bars, they are arranged closetogether in the center, as shown in Fig. l.

As all my improved features are used in connection with a single bar, adescription of one will answer for both, the same reference-charactersbeing employed on duplicate parts.

The draw-bar B runs the entire length of the car,and is adapted to havea limited longitudinal or endwise movement independent of the car, andis arranged a little below the bottom of the same, leaving the spacebetween the two, as shown in Fig. 2. The bar is supported at the ends inrelation to the ear by the cleat-brackets a a. The bar is also furthersupported and stiffened by the brace-rod B', which connects the twobearing-blocks aa3,in which the draw-bar slides, and the braces B2 B3,connected at one end to the blocks a2 c3 and the opposite ends to theaxles, as shown in Fig.2.

l The bar B is constructed in three parts and hinged or pivoted togetherat aa, which form of construction renders the barless rigid, and adaptsthe same to conform more readily to the movement of the car, and thusrelieve the line of draft from the jar incident thereto.

The ratehet-wheels C C are rigidly mounted on the axles A A2 and placedin the longitudinal center of the same. the draw-bar that moves back andforth above the ratchet-wheels is provided with the elongated slots b b,in which is located the pawl b2, pivoted to the draw-bar.

the draw-bar, serves to return the same to a normal position when thecar comes to a stop, as illustrated in the drawings, in which posi tionthe pawl or pawls b'Z are adapted to engage with the ratchet-wheels whenthe motive power is applied to the draw-bar, thereby causing thetruck-wheels to begin to move and make a partial revolution before thepower is transfer-red to the car proper. When the draw-bar hascompressed the spring D and reached the position in which it is held bythe motive power, the pawl or pawls bl become disengaged from theratchet-wheels, and the spring el prevents the same from having aclicking contact with said wheels as the car moves along in the usualmanner. When the strain is relaxed on the draw-bar, it is again returnedto a normal position by the means described, and when the motive poweris again applied the pawls engage the ratchet-wheels in the same manner,start the truck-wheels rolling, and relieve the power of thedead-weight, and so ou as often as the ear is stopped.

The spring D not only returns the draw-bar to a normal position, butalso relieves the horses or other power of any jerk or jar incident tostarting, as the spring is very gradually compressed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a car-starter, the combination, with a draw-bar adapted to have anindependent endthe cleatbrackets a a, the bearing-blocks a2 as, thebrace-rod connecting said blocks, and the brace-rods B2 B3, having oneend of each atwise movement relative to the ear proper, of

That portion of 6o The spring D, placed upon the draft end of tached tosaid blocks and the opposite ends to the ear-axles, whereby saiddraw-bar is supported in position, substantially as set forth.

1o draw-bar to a normal position, the paw] or pawls b2, the springs d,the ratchet-Wheels C C', the axles AA2, and Vthe truck-wheels, allconstructed, combined, and arranged to operate substantially as and forthe purpose set forth.
